New user fields

[Konnor88]

Hi all,

I have added the following new user fields to the user customization (and removed ones like Skype since that service isn't around):

Agentpedia account - You may now directly link your Agentpedia account in a field!
Discord - I have also added the ability for you to your Discord @ as well!
Favorite Microsoft Agent - Put your favorite MS Agent or whatever you can fit in that textbox in this one!
Operating System - Feel free to put your current OS in this field!

As the forum was just only revived today (we had one years ago but discontinued it) I am gradually theming it up and adding features, so feedback is appreciated!
